A Proposal for a Hierarchical, Scale-Invariant, Self-Causal Multiverse Framework: The Cosmic Tree Architecture

We present a qualitative cosmological architecture that synthesizes eternal inflation (the String Landscape), Everettian quantum mechanics (Many-Worlds), black hole interior cosmologies (Cosmological Natural Selection), and scale-invariant geometric closure into a single, self-consistent structural framework. By establishing a strict hierarchy between low-energy branching superpositions and high-energy boundary phase transitions, the framework eliminates friction between spatial multiverses and Everettian timelines. Furthermore, we address the Tolman entropy dilemma and avoid infinite causal regress by modeling the sub-Planckian boundary as a conformal, scale-dual mapping into the primordial background metric.
